The concept of link scheme is a system that you are linking
with some website with your site link to get Higher Page rank as well as
backlink that is totally pointless to other people.

Before introducing Google Penguin and Panda link scheme was
very useful to get Higher rank for website which is now useless. Because Google
considering those links as spam. Even they are deleting this types of blog as
penalty. So we should avoid to play a part
in Link schemes.

We are doing link scheme with our unconscious mind, e.g. if
you want to recommended a site by providing a link to that maybe useful for
your visitors, this action will include under link scheme.

We can say about reciprocal link that you are linking with a
site on the other hand you are including a link of that site in your blog. This
is totally bad concept and Google will detect this kind of link easily.

Good - Under Link
Scheme you are creating a link to a website and recommending for you visitors.

Bad - Under Link
Scheme you are creating a link intended to increase your site's ranking or
PageRank.

We get some site that we can publish a link easily but if
the site is spammy and you have linked with that site then your rank will ultimately
go down, not up. So you should evade the below movements to get ride from Link
Schemes.

Joining Paid Links

If you are purchasing link by paying then it is very bad for
your site. Initially you will get some backlinks but eventually it is useless
because Google has already penalized this kinds of website who are selling
links. Don’t think it will increase your rank rather your link will decrease or
it may lead to Google Penalty.

Participating in Extreme Reciprocal Links

If you are linking with another site and giving a link back
to that site that is called Reciprocal links. So if you do this kinds of Reciprocal
links extremely then Google will easily detect easily and that will make a bad
affect for your site.

Linking with unrelated or irrelevant websites /
webpages

This is another mistake that is doing by most blogger.
Suppose your site is related to Media and you have linked with a SEO site then it
would be treated as Link scheme because both sites are irrelevant to each
other.

Link exchange or Partnership links bidding

Some website give link exchange facility that is not a good
idea right now. Because by link exchange or partnership link building or
bidding your site will be affected by Google Penguin updates. Because of
changing of Google Penguin algorithm it is now affect your site reversely.

By preset services for linking

There are some preset service such as auto link building
service that purchased by you and there are some auto ping service that will
create bad effect for your site.

By using Text advertisements

If you use text advertisement by hidden link that will lead
to link schemes which is bad for your page rank. Though you are getting some traffic
and backlink but it will drop your page rank. Because the site that link to you
that may link to other spammy site which will make your text link spammy too.

Selecting low quality directory or bookmark service
for submissions

There are some new and low quality directory as well as
bookmark submission site where you can get backlinks by joining them. Those
sites are very bad for your rank because Google not only analyze your incoming
links but also analyze your outgoing links that plays a big role for your page
rank.

By giving comments with signatures to Spam forum

By giving comments in various you are doing link scheme.
Maybe those forums are spammy and you are unaware about them but Google must penalize
for this kind of link schemes.

Re-direction from one website to other web/blog pages
or site which is blocked by search Engine.

If you have crease some fake site only for making links or
redirect to your site that is also harmful for you. Because Google can detect
low quality and spam site. On the other hand if your site is blocked by search
engine then its effect will be more dangerous for your site.

Finally we can say only genuine and unique content make your
page rank higher. Some blogger think back link is the main responsible for page
rank but this is totally wrong concept because back-link has a partial effect to
get higher page rank. So just concentrate on quality content that can engage
your reader with your content for longer time and it will help to get higher
page rank and try to avoid all sorts of Link schemes.
